Abstract: The present invention relates to a façade system with a translucent porous insulating material of mineral or organic fibres for passive solar energy utilization, the insulating material having on the outside a coloured layer (2) for design purposes and for controlling the light transmittance. The façade system is formed from a multiplicity of preferably factory-prefabricated façade insulating boards (1). The coloured layer (2) can, moreover, be designed in such a way that it protrudes beyond the insulating layer along two board edges (3, 4). Consequently, when the façade insulating boards (1) are applied to the building wall, the abutting edges in the region of the joins between neighbouring insulating boards are covered by the overlapping protruding;  coloured layer (2).

Title: A nitrogen oxide storage catalyst
Inventor: STREHLAU WOLFGANG
IPC: B01J27/055
Filed: 1999-10-12
Granted: 2009-01-20
Abstract: The invention relates to a nitrogen oxide storage catalyst which contains at least one catalyst material and at least one nitrogen oxide storage component from the group of alkali and alkaline earth metals. The nitrogen oxide storage catalyst is characterised in that the nitrogen oxide storage component, after completing catalyst preparation, is present as finely divided barium sulfate, strontium sulfate or as a mixture or mixed crystals of the two sulfates or as their complete or incomplete decomposition product with an average particle size of less than 1 m. Barium sulfate and/or strontium sulfate act as feed materials for the active storage component barium oxide in the storage catalyst according to the invention. As a result of the reductive exhaust gas compositions occurring under normal driving conditions barium sulfate and strontium sulfate decompose to compounds which are able to store nitrogen oxides. This more or less compensates for the loss of active storage components which occurs due to ageing. There is also the possibility of decomposing barium sulfate and/or strontium sulfate during production by means of reductive calcination in order to obtain a high initial loading of the catalyst with storage compounds. In this case the sulfates mentioned are used as auxiliary agents in order to introduce the highest possible concentrations of storage compounds into the storage catalyst.

Abstract: The system and method of the invention relates to voice detection technology  for determining instants of time at which a snapshot of noise characteristic s results in improved adaptation of noise floors used in voice detection. The approach is based on the "lower envelope" of the smoothed input signal power . Incorporation of this approach in a simple time domain VAD (Voice Activity Detector) results in an effective low-complexity system which, on the basis of simulations, gives good performance down to SNR values of about 0dB. In the invention the lower envelope also provides the updated value of the noise threshold during the presence of speech. The invention can also be embedded in other, more complex (e.g., frequency domain) VADs at low computational cost.

Abstract: A shift control system comprises belt-speed calculation means, contact-circle enlarging pulley determination means, diameter-change calculation means, slip prevention thrust calculation means, speed ratio maintaining thrust calculation means and additional thrust calculation means. The diameter--change calculation means calculates the difference between the diameters of the contact circles at present and after a shift to a target speed change ratio, and the slip prevention thrust calculation means calculates a slip prevention thrust necessary for transmitting the power through a V belt without slip between the V belt and the drive and driven pulleys. The speed ratio maintaining thrust calculation means calculates a speed ratio maintaining thrust that is an addition to the slip prevention thrust for maintaining the current speed change ratio in constant condition and for transmitting the power without any slip of the belt, and the additional thrust calculation means calculates a shifting additional thrust that is added for the contact-circle enlarging pulley to achieve a shift to the target speed change ratio. The shifting additional thrust is inversely proportional to the running speed of the V belt, which is determined by the belt-speed calculation means, but is proportional to the difference between the diameters of the contact circles.
